Pre-Auction Analysis: November 2016, Christie’s Hong Kong

This Hong Kong pre-auction analysis, as always, focuses on visual elements that are not expressed on the GIA report, such as “inner-grade”, “undertone” and “color dispersion.” We use grades 1, 2, 3, 4 to evaluate these features.

It is often difficult to identify these characteristics when viewing stones in an auction catalogue, especially when the images are processed. All pictures in this review were taken with an iPhone 7
